I'm trying to add custom AMIs to my EKS cluster using solution as in https://docs.aws.amazon.com/eks/latest/userguide/eks-optimized-ami.html
Everything working good - CloudFormation is creating EC2 as in yaml but after that EC2 isn't join to my cluster. The cluster name filled in CloudFormation is exactly the same as name od cluster. How can to debug that or what can by wrong with that.
